Grundoram Manual (PDF 1.7MB) - TT Technologies Inc.

Technical SpecificationsA. Compressor System RequirementsAll tools require a compressor outlet pressure of 85-100 psi. TT Technologies suppliesair hoses that are sized to operate each GRUNDORAM model at its highest efficiency.Do not use smaller diameter hoses.If two compressors are used in parallel, place non-return valves between their outlets toensure that air is not being pushed from one compressor back into the other. Install thenon-return valves directly to the T-connector that joins the two lines together, and makesure that the non-return valves are facing in the proper direction (see Fig. 8).3.Air CompressorsGRUNDORAM ®Tool7' Connection HoseRolledHosesNon-ReturnValves7' Connection HosesWhip Check50'Air HoseDistributorLubricatorBall ValveFIG. 8: GRUNDORAM SET UP WITH COMPRESSORS (MINI-ATLAS—KOLOSS)WALL THICKNESSRECOMMENDATIONSPipe Minimum Wall ThicknessDiameter Bores up to 65 ft(20 m)Bores over 65 ft(20 m)in.

Install safety whipchecks on all air hose connections.Failure to do so could result inserious personal injury or death.B.
